## What it is
A Chrome browser extension that controls the playback speed of any HTML5 video or audio element on any website. It offers fine-grained speed adjustment (0.07x-16x), per-site rules, customizable keyboard shortcuts, and a draggable on-video overlay.

## Use cases
- speed up html5 video playback on any website
- watch youtube videos at 2x speed with keyboard shortcuts
- set default playback speed per site for lecture videos
- control netflix video speed beyond player limits
- speed up podcast audio in the browser
- stop websites from resetting my preferred video speed

## When to choose
- you watch lots of video or audio content in Chrome and want faster playback
- you need per-site default speeds or persistent speed settings
- you want fully customizable keyboard shortcuts for media control

## When to avoid
- you use a browser other than Chrome or Chromium-based browsers
- you need to control non-HTML5 media like Flash or native apps
- you want a standalone desktop video player with speed control
